The sexy Brooklyn model who was partying with Chris Brown and his crew before the big Rihanna-sparked brawl with Drake told The Post she was having the time of her life until all hell broke loose.

Ingrid Gutierrez, 21, and six sultry girlfriends arrived at the exclusive W.i.P. club around 3 a.m. on Thursday and were whisked right past the velvet rope and into a VIP section.

“It was crowded, and I wanted to go somewhere where I could just sit,” said Gutierrez, a curvy, 118-pound, 5-foot-6 brunette, with pink manicured nails who was wearing a low-cut mini dress that hugged her curves.

“We wanted to hear some hip-hop,” she said, “So we went to W.i.P., because we know everyone there and we knew that’s the kind of music they had.”

The club was jam-packed with revelers, and the women became separated.

She then bumped into a female friend she has in common with Brown — and landed two seats at the rapper’s table, where $2,000 bottles of Ace of Spades champagne were flowing like water.

“Each of them had a bottle and they were sharing them with us,” she said of Brown’s entourage.

They were also buying bottles for other tables — a gesture that would soon prove the powder keg for the massive melee.

“They were all so nice,” she said. “We were having such a good time. I was talking to my girlfriends, and I talked to Chris a little bit. I also talked to his bodyguard Big Pat.”

She didn’t recall much of what was said. “It was just small talk,” she said.

Gutierrez’s friend started making out with a member of Brown’s posse — and the girls were asked if they would be interested in joining them for an after-party at his suite in the swank Trump SoHo.

Gutierrez, who has a boyfriend of three years, just wanted to go home but agreed to the next venue for the sake of her friends.

“I was just there having a good time with my friends,” she said. “I wasn’t interested in any of the guys.”

“We were having so much fun,” she said — and everyone at the table was drunk and relaxed when the mood suddenly changed just before 4 a.m.

Brown asked a waitress to send a bottle of the bubbly to Drake’s table — and she came back with a piece of paper that Brown looked at and threw onto the floor.

That turned out to be the taunting Rihanna-referencing note that read, “I am f–king the love of your life,” sources have said.

Drake and a group that included rapper Meek Mill and their bodyguards then strutted over to Brown’s table.

“They got up in his face and were giving him the middle finger. Chris told Drake to f–k off, and the next thing I heard was smashed glass and the bottles started flying at us,” she said.

Someone threw a punch at Brown but was blocked by Big Pat — who suffered a big gash in his head.

“I didn’t see Chris act violently towards anyone,” she said. “Chris said, ‘Let’s go,’ but there were bottles flying and I saw him get hit in the face, so I hunkered down where I was.”

“Suddenly I feel this pain in my head and my friend is covering my face, trying to protect me,” she said. “And then everything was over. I’m laying bleeding on couch and we’re all freaking out.”

Another friend popped Gutierrez into a car service and they rushed over to NYU Medical Center, where she needed five staples to close a head wound.

By 6:30 a.m. the model was dropped off at her white BMW that she had parked near STK and drove herself home.

“My head is hurting so much,” Gutierrez said. She plans to sue the club and anyone else who is found liable.

Sal Strazzullo, attorney for Gutierrez, said, “A lawsuit will be filed against the club and every person who threw bottles and class, injuring my client.”

“I think Drake’s entourage are cowards for throwing bottles at girls,” she said. “I’ve lost all respect for Drake. Chris Brown acted like a gentleman to all the girls there. Chris tried to protect me and my friend.”

Rihanna, who was not at the club, has been partying elsewhere in the city this week — and yesterday was seen rolling into her Park Avenue hotel around 6 a.m.
